Functional reactive programming facilitates programming with time-varying data that can be perceived as streams flowing through time. Thus, one can think of FRP as an inversion of flow control from the structure of the program to the structure of the data itself. In a typical (say, imperative) program, the structure of the program governs how the program will behave over time; as time moves for...

Saito et al. (Modern Plastics 1997;74:175-7) have developed a low-cost transtibial prosthesis made of fiber-reinforced plastic (FRP). The prosthesis is comprised of an aluminum pylon, a cosmetic cover, and a constant cross-section composite foot into which aluminum supports are screwed to increase load-bearing capacity. Replacing these supports with a single integrated FRP stiffener significant...

We describe a language-centric approach to solving the complex, low-level, and error-prone problem of network control. Specifically, we have designed a domain-specific language called Nettle, embedded in Haskell, that allows programming OpenFlow networks in an elegant, declarative style. Nettle is based on the principles of functional reactive programming (FRP), and as such has both continuous ...

Fine roots (FR) play a major role in the water and nutrient uptake of plants and contribute significantly to the carbon and nutrient cycles of ecosystems through their annual production and turnover. FR growth dynamics were studied to understand the endogenous and exogenous factors driving these processes in a 14-year-old plantation of rubber trees located in eastern Thailand. FR dynamics were ...

Socio-economic status is a major indicator of livelihood and the two crucial factors determining livelihood are poverty and income inequality. The present study assessed the livelihood status of fishermen operating fibre re-inforced plastic (FRP) boats (motorised) of 9-10 m LOA. Socio-economic status, including poverty and income inequality of fishermen, comprising both owners (FRPO) and labour...

Synopsis: Advantages such as light weight, high mechanical properties and resistance to aggressive and chemical agents, non invasive installation, low tooling and machinery costs, possibility to repair the structure without interrupting its use have determined great expectation on Fiber Reinforced Polymer (FRP) composites for the strengthening of civil structures. However, their diffusion is of...
